Ross Detwiler was a relief pitcher for the Cincinnati Reds. In 2022 he struck out 28 batters over 26.1 innings across 30 appearances, going 0-2. His ERA of 4.44 was 12.0% higher than the league average of 3.97 — 9th of 21 on his team, and 359th of 546 among MLB pitchers with 20+ innings. Stripping out defence, his 4.94 FIP suggests that his ERA had some help behind him. He missed bats on 23.0% of swings (11.0% of every pitch he threw), walked 8.2% of the batters he faced and struck out 23.0%. His -0.1 dbWAR is built from that FIP rather than runs allowed, so it credits him for what he controls and not for the defence behind him.

How these are computed

wOBA uses linear weights measured from this season's own play-by-play rather than published constants, and wRC+ is park-adjusted against that same league. dbWAR is our own open implementation — not fWAR or bWAR — and the full derivation, including its simplifications, is on the methodology page.
